The Pi Cycle Top indicator uses two specific moving averages: the 111-day moving average (111DMA) and twice the 350-day moving average (350DMA×2). When the shorter-term 111DMA crosses above the doubled 350DMA, this crossover is seen as a potential signal that the market is topping out. The indicator’s name comes from an interesting mathematical coincidence: 350 divided by 111 is approximately 3.153, which is very close to the value of pi (π ≈ 3.142).
Origin and Mathematical Principle of the Indicator
The Pi Cycle Top indicator was created by Philip Swift in April 2019, who serves as Managing Director of Bitcoin Magazine Pro. This tool quickly achieved legendary status within the Bitcoin community due to its remarkable accuracy in identifying market cycle tops.
At its core, the indicator is relatively simple: it consists of two moving averages. The 111-day moving average (111DMA) reflects short-term price trends and responds quickly to price changes. In contrast, the 350-day moving average (350DMA) captures long-term trends, offering a smoother perspective on market movements. The magic of this indicator lies in the special relationship between the two lines. Historical data shows that when the 111DMA crosses above 350DMA×2, it often coincides with Bitcoin market cycle peaks. This crossover is considered a warning sign that the market may be overheating.
Historical Performance and Validation
Looking at historical data, the Pi Cycle Top indicator has delivered outstanding results. It successfully pinpointed the peaks of Bitcoin’s last three full market cycles, typically with a timing accuracy within three days. This track record has made it one of the most closely watched timing tools in crypto analysis. Specifically, during the 2013 cycle, the indicator accurately signaled a top before a major drop in Bitcoin price. The 2017 cycle also showcased its predictive power, providing a clear warning before a significant correction.
The double-top structure in 2021 provided another validation opportunity. The indicator’s signal aligned with the timing of the first peak, after which the market experienced a notable pullback. This consistent historical performance has strengthened traders’ trust in the tool. However, it’s important to note that the indicator’s effectiveness may change as the Bitcoin market matures. With the launch of Bitcoin ETFs and increased institutional adoption, the market structure is undergoing fundamental changes. These structural shifts could impact the predictive power of traditional cycle indicators.
Current Market Analysis
The current market shows some interesting differences from historical patterns. According to the latest analysis, several classic top indicators, including the Pi Cycle Top, have not yet signaled extreme overheating in this cycle.
As of February 2026, the two lines of the Pi Cycle Top indicator have not crossed. This matches Bitcoin’s current price behavior. According to Gate market data, Bitcoin (BTC) is currently priced at $76,473.9, with a market cap of $1.56T and a market dominance of 56.80%. Over the past 24 hours, the price has changed by -2.99%. Meanwhile, Ethereum (ETH) is priced at $2,277.55, with a market cap of $353.69B, a market dominance of 11.30%, and a 24-hour change of -2.97%. The overall market is in a correction phase, but typical cycle top characteristics have not yet emerged.
Other relevant indicators support this observation. The Puell Multiple is currently in a moderate range of 1–2, well below historical top levels. The Bitcoin Rainbow Chart shows the price in the yellow to orange bands, not yet entering the red "bubble" zone. The consistency among these indicators suggests the market may still be in the middle of the cycle rather than nearing its end.
Table: Comparison of Major Top Indicators in the Current Cycle
| Indicator Name | Principle Overview | Historical Top Performance | Current Cycle Status |
|---|---|---|---|
| Pi Cycle Top | Signal when 111DMA crosses above 350DMA×2 | Accurately warned at tops in last 3 cycles | No crossover yet |
| Puell Multiple | Ratio of daily miner revenue to 365-day average | Exceeded 7 in 2017, over 3 in 2021 | In 1–2 range |
| MVRV Z-Score | Measures deviation of market cap from realized value | Approached 10 in 2017, over 7 in 2021 | In neutral 2–4 range |
| Bitcoin Rainbow Chart | Uses log growth curves and color bands to assess value | Tops typically enter red zone | In yellow to orange range |
Calculation and Usage Guide
The Pi Cycle Top indicator is calculated using two moving averages. First, calculate the 111-day moving average of Bitcoin’s closing price by summing the closing prices of the past 111 days and dividing by 111. The same method applies to the 350-day moving average, using the past 350 days’ closing prices.
In practice, many trading platforms and data analytics websites have already integrated this indicator, so investors don’t need to calculate it manually. The key is to watch for when the 111-day moving average crosses above twice the 350-day moving average. When this crossover occurs, it’s traditionally seen as a market top signal, indicating that price appreciation may be outpacing fundamental support. However, it’s crucial to emphasize that no single indicator should serve as the sole basis for trading decisions.
To use this indicator effectively, incorporate it into a broader analytical framework. Combining it with other technical indicators, such as RSI or MACD, can offer a more comprehensive market view. It’s also essential to consider on-chain data, market sentiment, and macroeconomic factors.
Understanding the Indicator’s Limitations
Despite its impressive track record, the Pi Cycle Top indicator is not infallible. Like all technical analysis tools, it can produce false signals in volatile market conditions. Traders who rely solely on this indicator may make decisions based on inaccurate predictions. Its effectiveness also faces challenges from changes in market structure. As Bitcoin becomes more integrated into the global financial system and is influenced by institutional capital and ETF products, its price patterns may shift. Traditional cycle indicators, which were designed for retail-driven markets, may experience diminishing marginal effectiveness.
Some deviations from traditional patterns have already been observed in the current cycle. For example, the supply held by short-term holders (STH) has risen to about 5.5 million BTC, but the price peak occurred on October 6, 2025, diverging from the STH supply peak. This change may reflect a shift in the market participant structure. Investors should avoid over-reliance on any single indicator. A balanced approach includes combining fundamental analysis, multiple technical indicators, and sound risk management strategies. The market is always uncertain—flexibility and adaptability are key to long-term success.
Based on current data, several top indicators have not yet reached historical extremes. According to the latest Gate market data, Bitcoin’s market cap remains at $1.56T, despite minor adjustments over the past 24 hours. Market analysts have observed that steady institutional inflows in this cycle may be changing Bitcoin’s price dynamics, challenging the effectiveness of traditional cycle indicators. The Pi Cycle Top lines have not crossed, and other indicators like the MVRV Z-Score remain in the neutral 2–4 range, all suggesting the market may not have topped yet.
As the cryptocurrency market continues to evolve, the risks of relying solely on historical patterns for predictions are increasing. Investors need to combine classic indicators with a deep understanding of market structure changes to better navigate this increasingly complex new financial landscape.
